Subject:
TWP/QCRAD/C2 - Instrument grounding problem
DataStreams:twpqcrad1longC2.s1, twpqcrad1longC2.c1
Description:
A grounding problem with the skyrad data logger (discussed in DQR D090605.2) created 
intermittent anomalous voltages and incorrect data. Days listed in this DQR are periods where 
bad data could be clearly identified; data from other days in this date range should be 
treated with caution.
Suggestions: 
Data is suspect during this time frame and cannot be corrected.  Disregard all qcrad 

data during this time frame.
